Abstract
The utility model relates to an inorganic liquid stripping tower, which is suitable for the caprolactam production process by means of phosphate hydroxylamine oximate, the utility model is characterized in that: an improved valve tray is used in the stripping tower, the tray adopts the rectangular float valve, the tray is opened with holes, and the tray is arranged according to a certain distance. The tower root has entrainment and flooding problems in the stripping tower, the production of the device is continuous and stable, thus avoiding the increased consumption and parking of the device due to the art control fluctuation, and gaining good economic benefits and social benefits. The benefits gained every year can reach RMB3.70 million.
Description
The utility model relates to a kind of inorganic liquid stripper, is applicable to the production process by hydroxylamine phosphate oximation method system caprolactam.
Inorganic liquid stripper is the key equipment in the inorganic closed circuit of hydroxylamine phosphate oximation method system caprolactam route, and traditional design is a sieve-plate tower.When the production load is higher, particularly under the full production condition, inorganic liquid stripper often takes place carry secretly and general tower phenomenon, make caprolactam device integral production shakiness, and then cause the device load to descend, material consumption is increased, cause heavy economic losses.Calculate with 50,000 tons of/year caprolactam production apparatus, general 1 year accumulative total take place the general tower of stripper reach 10 surplus time, lose time altogether and be 5--6 days, reduce load 5%, accumulative total reduces caprolactam output and reaches 300 tons, surplus direct economic loss reaches 330 ten thousand yuans, increased device consumption of raw materials simultaneously and also increased production cost, cause significant loss reach 40 surplus ten thousand yuan.At present, all there is this problem in the caprolactam production apparatus with technology both at home and abroad, does not all find reasonable processing method, illustrates in this hydroxylamine phosphate oximation method technological process to have certain deficiency.
The purpose of this utility model is to provide a kind of improved inorganic liquid stripper, and the elimination stripper is carried the problem with general tower secretly, makes device produce continous-stable.
The utility model is achieved in that in stripper and uses a kind of improved valve tower column plate, perforate on the column plate, and this column plate is installed according to a determining deviation.The float valve that this column plate adopts is a rectangle, and guide effect is arranged, and the layout of float valve makes up according to process characteristic, and its column plate both sides prerotation vane is parallel to inorganic liquid flow direction cross section and perpendicular to the flow direction of inorganic liquid blanking, middle part prerotation vane direction is staggered.
The utility model is further described below in conjunction with accompanying drawing:
Fig. 1 is the stripper structure diagram.
Fig. 2 is the float valve structure chart.
Fig. 3 arranges schematic diagram for the column plate float valve.
Stripper shown in Figure 1 partly is made of tower shell 2, column plate 1 etc., in the column plate There is the polylith column plate in section, and column plate is fixed on the tower shell, and the installing space between each plate is 500-700mm, best mounting distance is 550-630mm, and many float valves are arranged on the column plate.
Fig. 2 is float valve structure figure, and float valve is arranged on the column plate, may have one or more Pilot hole, left figure are the guide float-valve of 1 pilot hole, and right figure is leading of 2 pilot holes To float valve. Wherein: 1 is the column plate part, and 2 is guide float-valve, and 3 is prerotation vane. Guiding Float valve and column plate are assembled together, and can move up and down during work. Open for column plate at middle part 4 The hole, its percent opening scope is 3-13%, the best is 7-12%.
Fig. 3 arranges schematic diagram (take the float valve of 1 pilot hole as example) for the column plate float valve, Wherein 1,2 is guide float-valve, and 3 is liquid reducing hole, and 4 is the cofferdam, as shown in the figure, and big arrow Head is oriented to the liquid flow path direction, and small arrow is oriented to the prerotation vane direction, as seen: a column plate left side, The float valve prerotation vane on right both sides points to liquid flow path direction (as shown by arrows), and the middle part float valve is led Be staggered to the sheet sensing, adjacent pilot hole points to respectively different directions.
The utility model only needs a small amount of investment to eradicate former hydroxylamine phosphate oximation method stripper and carry problem with general tower secretly with regard to thorough, avoided because the consumption that the technology controlling and process fluctuation causes increases and device stops, strengthened the operating flexibility that hydroxylamine phosphate oximation method is produced the caprolactam device, good economic benefit and social benefit have been arranged.
Embodiment 1: new column plate is installed in hydroxylamine phosphate oximation method produces in the inorganic liquid stripping Tata of caprolactam device, the valve plate of tape guide is housed in this tower, the prerotation vane of two edge float valves points to the liquid flow path direction, middle part float valve prerotation vane points to and is staggered, distance between plates is in the 600-620mm scope, percent opening is 10%, column plate install to adopt clamp to connect and in addition bridle iron fix.Device puts into operation, makes inorganic liquid enter new stripper, and this device is not carried secretly and general tower.
Claims (4)
1. an inorganic liquid stripping tower is applicable to by the production process of hydroxylamine phosphate oximation method system caprolactam, it is characterized in that: in stripping tower, use a kind of improved valve tower column plate, and perforate on the column plate, and this column plate is installed according to a determining deviation.
2. a kind of inorganic liquid stripping tower according to claim 1, it is characterized in that: the float valve that this column plate adopts is a rectangle, its column plate both sides prerotation vane is parallel to inorganic liquid flow direction cross section and perpendicular to the flow direction of inorganic liquid blanking, middle part prerotation vane direction is staggered.
